Early Rehabilitation of COPD Patients in ICU

• Mortality at day 28 and day 90 [ Time Frame: Measured within the ICU stay of the patient ] [ Designated as safety issue: No ]
• Length of stay in intensive care unit and hospital [ Time Frame: Measured within the ICU stay of the patient ] [ Designated as safety issue: No ]
• Clinical measurement of muscular strength in lower limbs(day 0-2 and day 28-30) [ Time Frame: Measured within the ICU stay of the patient ] [ Designated as safety issue: No ]

Twenty per cent of the intensive care patients mechanically ventilated suffer from chronic obstructive pulmonary disease (COPD). These patients stay longer in Intensive Care which is more costly and they are more prone to nosocomial infection.In addition, they are longer bedridden and they develop muscular weakness.Prolonged inactivity results in respiratory and skeletal muscle weakness which curtails simple daily activity.The principal purpose of this study is to compare two types of muscular rehabilitation (electrical stimulation of the thigh and/or cycloergometer training) to classic passive mobilization of the leg.The second purpose is to analyse the effects of each type of rehabilitation on muscular fiber (structural and functional analysis) by muscular biopsies.Two hundred forty COPD patients admitted in the intensive care unit for acute respiratory failure will be randomized in 4: 1 fashion to receive passive mobilization of the legs(group 1, n=60), electrical stimulation of the thigh (group 2, n=60), cycloergometer training (group 3, n=60) or electrical stimulation of the thigh and cycloergometer training(group 4, n=60).The rehabilitation program will last 4 weeks with 5 sessions per week.In each group of patients, muscular biopsies will be done under local anaesthesia at the beginning and end of the rehabilitation programme and when they are discharged from the service.
